Serial No. 547,001.

To all whom it may concern:

Be it known that I, EDWARD Y. Moonn, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in TrolleyHoists, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to a trolley or trolley hoist adapted to travel on a trackway and support a load.

The primary object of the invention is to provide the trolley in such form that it may be easily and conveniently removed from the trackway whenever desired without the necessity of shifting it beyond the end of the trackwa-y.

To this end, the invention comprehends the combination with the other members of the structure, of a movable side member carrying a supporting wheel, whereby the structure may be freed from the track by the movement of such member. The particular means herein shown and their equivalents for carrying out this operation are also included within my invention.

My trolley is well adapted for combination with a hoisting mechanism carried thereby, though it is to be understood that the invention is not limited to such construction.

The drawings clearly disclose my invention embodied in a combined trolley and hoist. The complete structure shown includes an efficient device for clamping the trolley to a trackway, and includes also a cooperative arrangement of the trolley with branch tracks whereby it may be thrown without the use of a switch. These additional features are not claimed herein, but in my divisional applications Serial Numbers 579,326 and 579,327, respectively, filed August 27th, 1910.

Figure 1 is a side elevation of the combined trolley and hoist, including the upper portion of a suitable grapple carried by the hoist; Fig. 1 is a sectional detail on the line aa of Fig. 1; Fig. 2 is an end View of the trolley and hoist; Fig. 3 is a horizontal section through the web of an I-beam support at the junction of two branches; Fig. 4 is a side elevation of the supporting track shown in Fig. 3; Fig. 5 is a vertical section through the trolley and hoist and through the supporting track; Fig. 6 is a perspective view of the clamping mechanism removed; Fig. 7 is a longitudinal cen tral section through the hoist mechanism, showing the clamping device; Fig. 8 is a perspective view of the clamping lever; Figs. 9 and 10 illustrate a modified form of the trolley side, Fig. 9 being a sectional side elevation of the upper portion of the trolley, Fig. 10 being a cross section through the trolley.

Referring, by numerals, to the structures shown in the drawing, 11 represents the web and 12 the lateral bottom flanges of a suitable I-beam support for the trolley. This I-beam is adapted to have branches, as illustrated at 13 and 14 in Fig. 3. At the junction of the branches with the main trackway, the track is peculiarly formed in a way which cooperates with the peculiar trolley structure, as will be hereinafter more fully explained.

The trolley frame comprises a pair of members 2021 which are adapted to stand beneath the I-beam flange 11 and carry the load-supporting mechanism. These members are rigidly secured together, as for example, by the bolts 22, 23 and 24, which pass through the members and abutting bosses formed on their inner sides. The frame portion described is supported by up wardly extending side members 26 and 30, which carry two pairs of wheels 27 and 32, adapted to ride on the flanges 12. The rigid body 2021 supports the load-holding or raising mechanism. Such mechanism, in the form shown, is of a hoisting character and is carried by downward extensions 28 and 29, of the members 20 and 21, respectively. The hoisting mechanism shown will be hereinafter described.

The trolley, as shown, is carried by two wheels 32 on one side of the I-beam, and two wheels 27 on the other side. The member 26, which carries the wheels 27 is rigid with the member 20, and may be an integral portion thereof. The member 30, however, which carries the wheels 32, is hinged to the member 21 to allow the wheels, on that side, to be turned down so that the mechanism may be removed from the trackway at any desired point. As shown in Figs. 1, 2 and 5, the supporting member 30 is a U- shaped structure carrying two studs, which constitute the wheel axles and having portions depending beneath such axles. These two depending portions are keyed on a 10ngitudinal rock shaft 85, journaled in the block 21. On the end portions of this shaft, beyond the block 21, are keyed two rock arms 87 and 88, each of which has a boss 89 in which is mounted a plunger 40. This plunger is pressed inwardly by a spring 41 surrounding its shank, and in its innermost position, occupies a recess in the corresponding end of the block 21. On the outer end of each plunger is a suitable knob or handle 42. lVhen the plungers are in their respective recesses, the hinged structure, comprising the arms 87, 88, the rock shaft and the side member 00 is rigidly locked to the frame block 21, and accordingly the wheels 32 are held in the same presentation to the supporting track as the wheels 27 carried by the rigid side member 26. The plungers 40 have their engaging ends preferably tapered, as shown, so that, under the action of their springs they cause a firm locking of the pivoted side.

The construction described enables the hoist to be conveniently removed from the track at any point. It is simply necessary to pull outwardly on the two knobs 42, withdrawing the plungers 40 from their respective sockets and allowing the pivoted side structure to swing away from the track. This is a valuable feature, as it enables the track to be continued clear up to a transverse wall, it being unnecessary to provide any clear space at the end of the track for installation and removal of the trolley.

As heretofore stated, one of the objects of this invention is to provide the trolley and track in such form that the trolley may be enabled to pass with the greatest ease from a main portion of the trackway to different branches. I achieve this result, partly by arranging the track as shown in Figs. 3 and 4, and partly by the trolley structure. As shown in Fig. 8, two branches l3 and 14 of the track are I-beams having their flanges separated from the flange 12 by gaps, designated 15 and 16, the flange of the main track portion being brought to a point, as 17, between the two diagonally cut ends of the flanges of the track portions 18 and 14. By this means the passageways 15 and 16, referred to, are formed. The edge of the point portion 17, adjacent to the passageway 16, is parallel with the corresponding edge of the track portion 13. The same is true with the other edge of the point 17 and the track portion 14. Adjacent to the track junction, the web 11 is cut away, while, on the branches, the web is also cut away. The combined opening through the main and branch webs may take the form illustrated at 18, in. Fig. 4. The opening 18 and the passages 15 or 16 enable the trolley traveling on the main track to be passed to either of the branch tracks, the correspond ing side member 30 or 26 of the trolley passing through the opening 15 or 16, as the case may be. The angles of the gaps 15 and 16 are so arranged, with reference to the trolley wheels, that in passing across these gaps, only one wheel passes at a time, so at least three of the wheels are always supporting the load. lVhen the trolley on the main track arrives at the entrance to the passageways 15 and 16, it is simply necessary to push or pull it by hand, one side or the other, to determine which passageway is ta be entered. As soon. as the correspondin side has come into engagement with the one of the flange of the corresponding branch track, the pathway is determined. In the movement from either branch to the main trackway, the passage is automatic without the necessity of lateral hand shifting. The depending members of the frames 26 and 30 are beveled at their edges, as shown at 26 and 30, which facilitates the passage of the trolley from the main track to a branch track.

To enable the trolley to stand closely alongside of the track at all times, and, at the same time, to easily pass the salient angles 19 of the main flange, where the point 17 begins, I may form the side supports in a U-shape, as heretofore described with reference to the support 80 and as shown in Fig. 1. With such structure, when the wheel base is twisted out of alinement with the main trackway in passing to or from a branch, the projecting point 17 will stand within the space between the depending arms of the side members so that there is no binding at such points. It is to be un derstood that the side members 26, though rigid with the blocks 20, are formed in correspondence with the side members 80, being U-shaped in the structure shown in Figs. 1, 2 and 5.

In place of making the trolley supports 20 and 26 U-shaped, they may be made T- shaped, as shown in Figs. 9 and 10, the distance across the shank portion of the T being short enough so that the frame can twist about the track points 19 without binding. Referring to Figs. 9 and 10, the T- shaped side member 45 is shown as carrying the wheels 82 and as pivoted to the block 21 by a hinge pintle 46. The side member 45 is locked in place by plungers 48, mounted in the block and adapted to occupy recesses in the ends of the outwardly eXtending boss 44 on the side member. These plungers are shown as pressed inwardly by springs 47 and may be drawn outwardly by heads 49.

The above described construction, it will be seen, is very simple, and, of course, a similar arrangement may be employed, if desired, with the U-shaped side member shown in Fig. 1. The member 50, in Fig. 10, which carries the wheels 27 on the opposite side, is a rigid and preferably integral it is only necessary to throw out the lever port-ion of the main frame block 20. It is 62, and the clamping takes place at once, to be understood that this plate 50 partakes automatically, and very effectively, as has of the same T character as the plate 45. been demonstrated by actual practice. The members and will have beveled When the parts are in their normal un edges, as indicated at 45, for the same purclamped position, the flat portion 74 of the pose as the beveled edges 26 and 30 lever 62 stands against the face of the bosses To efficiently lock the trolley at any de- 57, thereby preventing any accidental applisired point, I provide mechanism carried by cation of the clamp, the first outward movethe frame 20 and 21 and adapted, when acment of the clamp drawing the shank 61 tuated, to rise into binding contact with the outwardly a short distance before the curved under side of the I-beam flange.

These 5 65 clamp. Accordingly, to throw on the clamp, cross bars are rendered conveniently accessible by being cranked, as shown, the cranked ends being squared, as at 99, and mounted in corresponding openings in the frame members 28 and 29.

It will. be seen that, by the construction described, I have provided a very simple and compact trolley hoist. This hoist requires a minimum amount of head room and very efficient in raising the load. The trolley enables the hoist to be shifted about on the tack, as desired, and, by reason of the clamp, may be locked at any point. By drawing out the spring pressed plungers described, the hinged side of the trolley may be turned down to remove the structure from the track. If this removal is accomplished by turning down the hinged side while the other side is standing within the opening 16 where the track branches, the removal may be very conveniently accomplished 'by one man, for the branch track will hold the hoist on the flange after the opposite side is turned down, and then the operator may take hold of the hoist on the other side and shift it lengthwise until it is free from the holding influences of the branch track, when he can let it slide off the flange.

Having thus described my invention, what I claim is:

1. In a trolley, the combination of a frame adapted to stand beneath a supporting trackway, a side member rising from the outer side of the frame, a pair of supporting wheels carrying said side member, a second side member pivotally secured to said frame at its other side and beyond the trackway, and a pair of supporting wheels carrying said second side member.
